The long-lasting “war on drugs” has not prevented the increasing drug supply and use, and yet drug-related law enforcement costs over US$ 100 billion a year. According to the Open Society Foundations report, the focus on drug law enforcement limits options for other areas of expenditure, such as harm reduction. This report produced in 2013 provides an overview of the costs inflicted by the “war on drugs” and argues that drug law enforcement is exceptionally poor value for money and, therefore, not justified.
